This issue affects all three servers.
When the Oracle Solaris miniroot is enabled, starting the Oracle ILOM Remote System Console Plus storage redirection will fail with the following console error message:
Command failed to complete...Device is gone.
After the storage redirection fails, the Oracle Solaris OS miniroot will eventually reconnect to the server.
Recovery
Disable the miniroot redirection prior to starting the Oracle ILOM Remote System Console Plus storage redirection. When remote storage redirection is no longer required and the remote storage redirection has been disconnected, reactivate the miniroot redirection.
Disable miniroot redirection.
-> set /SP/services/kvms/host_storage_device mode=disabled
Start the Oracle ILOM Remote System Console Plus storage redirection.
For instructions on starting the Oracle ILOM Remote System Console Plus storage redirection, refer to the Oracle ILOM Administrator’s Guide for Configuration and Maintenance Firmware Release 4.0.x.
Reactivate the miniroot redirection.
-> set /SP/services/kvms/host_storage_device mode=miniroot
